is this the stock O2 sensor? looks alot like a wideband. Also, the wiring is weird:



the two black wires coming off the sensor go to this plug, and the blue one goes into the cam wire cover panel thingy.


Is this the stock'er or a wideband?

It is indeed a stocker...

Pretty sure that blue wire is supposed to go into the plug though... What is the blue one? What reason would they send it somewhere else?

stock. ive never seen a flanged wideband before, but they may exsist. regardless, wideband 02's are 5 wire, not 3.
as far as the wiring. the blue wire is signal, one black is ground and one black is heater (can use either black).

Yeah thats stock, but 2 other things. You might want to replace the black frayed hose next to the turbo in the first pic. And secondly, is that a soda bottle cap your using as a vacume cap on the accordian hose in the secong pic?

Ok, from your pictures, it appears that you have a few (or will shortly) problems going on. First, re-route that black hose by the turbo. Where the hell does it go? You are experiencing that hose to ~1000 fahrenheit temperatures repeatedly and it will soon fail.
Next, solder those O2 wires back to the connector and put some heat wrap over those three wires. they are also exposed to extreme temperatures and are likely already brittle.
Lastly, get rid of all the electrical tape holding things together!!! Buy proper clamps and covers for things like your accordian hose ports. It looks better and you won't run the risk of sucking something unwanted into your turbo/throttle body/engine.

^ What he said And install the upper bracket (#2 turbo stay is what Toyota calls it) The missing "stay" mounts to the top of the turbo in the open hole to the open hole in your head. It's part 17297 in this illustration:
